    ANy alteration of enviroment would result in a change in the rate of plant growth, and also the health of the plant itself. However, how exactly does the pH of the water affect? So far I have only gathered a few points:

    1. It's very obvious that if too acidic or alkaline, the roots and even the cells would be damanged due to the corrosive proptery.

    2. The strong base or acids may contaminate the minerals the plants need.

    3. The pH of the water would determine the rate of active transport or diffusion as it affect the water concentration.

    Is there any other points? Please help me with this question...

    I guess any organism living in symbiosis with the plant could be affected, indirectly affecting the plant. I don't know if that is an actual problem in nature, though.


    ...Wait, what?

    Depends what plants you are on about.

    Plants adapt and thrive in a variety of conditions, and some prefer acid soils and some alkaline.

    Marijuana for instance doesn't like acidic soils (unless you want a male) whereas azaleas love it.

    The main effect is due to the solubility of plant nutrients in water, which varies with pH. The nutrients are not available for use by the plant unless they are dissolved. Excessive acidity will also dissolve metals that can be toxic, and can kill beneficial bacteria.

    Too much acid can also send you mad

    I've come across this during the research. Seems to be quite interesting, albeit slightly off-topic to this thread.

    Thank you for your answers :-D

    Hey thanks

    That's interesting to know.

    Next time i get poorly plant perhaps i'll try dissolving an aspirin in water and spraying the leaves. Worth a try!
